Invalid zip file created from "append" (archiver@5.3.1)

Append doesn't work entirely, doesn't matter what you include. It even doesn't work for strings. Minimal example:

cost archive = require('archiver')("zip")
archive.append("hello", { name: "test.txt" })
archive.finalize()
archive.pipe(require('fs').createWriteStream('example.zip'));

This produces a zip with CRC error.

I'm using Node 16 on Windows.

I'm also running into issues with Windows. Getting duplicate files in the zipped archive. On Mac, it works fine... not sure of the cause yet.

it's likely order of operation issue, to get data flowing/streaming you need to pipe to file first before appending
